From the New York Times, 5/1/1865

THE LIBBY PRISON SIGN.

Adamsí Express Company to-day brought from Richmond the Libby Prison sign,
which has been taken down and forwarded here for safe keeping. This sign, a
plain unornamented board, was nailed up against the end of the prison building,
and bears the inscription "L. LIBBY & SON, Ship Chandlers." What use is to be
made of this relic is not stated.
